Setting and analysis of vmivoi information management model

analysis of basic concepts of VMI

VMI, namely vendor managed inventory, is an important strategy for suppliers and user enterprises to optimize the management of supply chain inventory. Its basic implementation form is: the supplier and the user enterprise share the enterprise's inventory and consumption data in a certain way (for manufacturing enterprises, it generally refers to production collection; for commercial channels, it generally refers to sales shipment), according to a certain replenishment strategy (such as dynamic or static safety inventory, order point, reorder quantity and other control parameters), independently determine the supply plan, and quickly and effectively replenish the user enterprise

vmi management mode is developed from QR (quick response) and ECR (efficient customer response). Its core idea is that suppliers make actual replenishment according to the actual consumption model, consumption trend and replenishment strategy by sharing the current inventory and actual consumption data of user enterprises. As a result, both sides of the transaction have changed the traditional independent forecasting model, minimizing the waste of business flow, logistics and information flow caused by the uncertainty of independent forecasting, and reducing the total cost of the supply chain

in VMI mode, the control of the enterprise's purchase and replenishment is the corresponding supplier. The spontaneous and active distribution and replenishment of suppliers in commercial distribution channels can be seen as a concrete embodiment of this model. The key to its realization lies in the timely acquisition of inventory and transaction data of user enterprises by suppliers. For this, the author will comprehensively discuss it in the special topic of channel data collection and management

voi basic concept analysis

voi, namely vendor owned inventory, is a common mode for enterprises to achieve zero inventory supply. Its basic implementation form is: the supplier organizes goods preparation according to a certain plan, and replenishes materials to the warehouse that can be directly accessed by the enterprise. At this time, the ownership of the corresponding material still belongs to the original supplier, which is not an enterprise asset. However, enterprises can collect at any time according to their own needs, and realize the transfer of property rights when collecting and issuing. Finally, the enterprise settles with the supplier according to the actual collection amount according to the agreed settlement period

it can be seen that the core of the VOI model is the change of the transaction business model by both parties, which leads to the change of the logistics model. From the perspective of the whole implementation stage, it is the planned business model coordination between the two sides first, then the logistics movement is realized, and finally the business flow operation is realized during the actual consumption. In the VOI management mode, although the ownership of materials still belongs to the supplier, the use control belongs to the user, and this part of inventory must also participate in the material planning calculation of the user's enterprise. This management mode is equivalent to consignment in sales channel management for suppliers; For enterprises, these inventories are entrusted by suppliers and are voi. In this way, in practice, enterprises can do voi collaboration with upstream suppliers and consignment management with downstream customers at the same time

voi management mode realizes zero financial inventory and zero pre delivery supply of materials for user enterprises. At a glance, suppliers are in a completely disadvantageous position. However, through the effective collaboration of enterprise and supplier planning information, suppliers can organize their own production and supply in a more orderly manner, so as to control production and logistics costs. In a certain mode, you can further reduce your storage management costs

vmi, voi comparative analysis

vmi and voi are both aimed at the management of supplier related inventory, which are often confused in practical application. From the perspective of basic concepts and practical application, there are still great differences between the two:

· VMI, to a greater extent, is a change in the replenishment and response mode of suppliers; Voi highlights the changes in the transaction mode of suppliers and user enterprises. And the replenishment modes of the two are not the same

· under VMI mode, the main control of inventory is the supplier; Under the VOI mode, the main control of the warehouse is in the user enterprise

· in VMI mode, the ownership of supplementary goods belongs to the user enterprise by default; In the VOI mode, the ownership of the supplementary goods still belongs to the supplier before the user actually collects them

· VMI mode is common in the relative supply chain environment with suppliers as the core, and the dominant power is the suppliers; Voi is common in the supply chain Format dominated by user enterprises

of course, nothing is absolute, and these two modes can also be moderately integrated in practical application, because there is no strict restriction in the management model of VMI and it will not restrict that the ownership of goods must belong to users. In this way, the supplier can obtain the relevant inventory and transaction data of the user with the permission of the user enterprise, and automatically replenish the goods according to the agreed rules of both parties. The ownership of goods still belongs to the supplier by default, and the transfer of property rights can be realized after the actual collection. We may take a new term, VIM, vendor inventory management

comparing the theoretical models of VMI and voi, it can be seen that voi has a more significant impact on enterprises and enterprise management systems. The following chapters of this paper focus on voi management issues. It mainly includes: replenishment mode of voi, warehouse management under voi mode, system adjustment under voi mode, etc

voi replenishment plan mode

voi management model, the key to its implementation lies in the plan information collaboration between the enterprise and the supplier (the premise is the business collaboration between the two). The enterprise, that is, the demander, should publish its own needs to the supplier in a certain form, and the supplier should actively replenish according to the plan. There are generally two common forms of plan release:

Product plan and BOM mode

enterprises release product demand plans regularly or irregularly through their own network system. The supplier logs into the system through the client opened by the demander, selects the product plan by himself, and calculates the MRP according to the BOM to generate the real-time material demand plan. Suppliers can download or synchronize the demand plan to their own information system, replenish goods according to the recent demand of the demand plan, and organize goods preparation according to the medium and long-term demand

there are certain conditions and restrictions in the use of this mode: the current inventory of materials and the inventory of semi-finished products, as well as the related expected receipt and delivery, are not considered in the calculation; A material has only one voi supplier in a specific BOM. After the plan is expanded, each supplier only sees its own needs; Alternatively, the user enterprise defines a supplier BOM for this kind of material, and each supplier performs demand calculation according to its own supplier BOM. Whether it is a standard BOM or a supplier BOM, it is transparent to the supplier by default. The supplier can directly select the product plan calculation

therefore, this model is more applicable to the BOM structure of enterprises, which is simple (there are few levels, or the middleware is all virtual, or the middleware does not consider the actual inventory), and has certain requirements for the update of product plans. At the same time, although the BOM has been treated as a supplier and transparent, there is still a risk of disclosing the company's secrets. Therefore, it is particularly suitable for the company's own transactions within the group

purchase plan mode

enterprises remind themselves through the demander that they can enlarge the experimental curve and re confirm their network system by "yield point", and publish the material demand plan or purchase plan for each supplier regularly or undefined. The supplier logs in to the system through the client opened by the demander to query the enterprise's purchase plan, and then replenish according to the recent demand of the demand plan, and seek to organize its own stock production plan according to the medium and long term. Of course, when the enterprise's information system cannot provide effective support, you can also download files through the station or send them directly in the form of email. If the application data interconnection between enterprises can be realized through data pretext or even EAI mode, the implementation of this mode will be more promoted

with this mode, the enterprise, that is, the demander, needs to calculate the material demand plan first, then allocate the demand plan of each supplier according to certain rules, and finally publish the purchase plan for each supplier. After logging in, suppliers can only see their own plans

this mode is widely used, especially in large manufacturing enterprises, because it hides many management details of the demander

in the implementation of voi management and pre-sales projects (involving tobacco express fee, motorcycle machinery, battery energy, automotive power and other industries), which the author has personally participated in for several years, the second mode is basically adopted, that is, the procurement planning mode. Some of them first adopted the first mode and then converted to the second mode. Of course, in practice, the mode of regular synchronization and strategic replenishment of inventory and transaction data in VMI management can also be adopted, but the requirements for system interconnection, consistency and synchronization are higher

voi warehouse management mode

in the VOI management model, from a relative stage, there is logistics first and then business flow. For warehouse management in logistics, there are several main modes to choose in actual business:

· suppliers directly use the enterprise's own warehouse, and the enterprise is directly responsible for the receipt and delivery of the warehouse. Suppliers do not need to clarify the details of inventory storage and management, nor do they need to pay warehouse management fees and rents to the enterprise; This is also the most acceptable voi implementation for suppliers

· the supplier directly uses the enterprise's own warehouse, and the enterprise is directly responsible for the receipt and delivery of the warehouse. The supplier does not need to clarify the details of inventory storage and management, but needs to pay the warehouse management fee and rent to the enterprise

· suppliers rent or build their own warehouses near the enterprise. They are responsible for the receipt and delivery management of the warehouse and bear the cost of inventory maintenance, but the receipt and delivery records must be synchronized with the management information system of the user enterprise

· suppliers rent the warehouses of other professional logistics companies and entrust them to do the overall logistics management. The logistics companies are fully responsible for the transportation, warehousing, distribution, packaging, loading and unloading, circulation and processing and other logistics activities of corresponding materials. In today's third-party logistics management and enterprise zero warehouse trend of thought, this mode of metal components will be all damaged is becoming more and more common. This requires suppliers, user enterprises and logistics companies to achieve effective data sharing and synchronization

at present, in the management of group enterprises, a logistics company gradually appears to unify the logistics management of material transportation, warehousing, distribution and so on, and provide logistics services for multiple manufacturing companies at the same time. Suppliers directly entrust materials to logistics companies for management. Logistics companies collect experimental machines from suppliers and manufacturing companies, and the electromechanical operation is controlled by servo speed regulation system to collect logistics costs. This is also an implementation form of group voi

main impact of voi on information system

in addition to the previous information release and synchronization, other impacts of voi model on enterprise management information system are mainly in inventory management and a/P settlement

inventory management

in the traditional enterprise management information system, the materials in the warehouse are the enterprise's own inventory, or the materials that the enterprise is checking and waiting to transfer. In this mode, the information system does not need to distinguish which inventory belongs to the supplier and which belongs to the enterprise itself. The VOI model subverts this assumption, that is, at this time, some materials in the warehouse are owned by suppliers, some are owned by themselves, and there can be many suppliers
